ZeniMax, the parent company of game publisher Bethesda, has been sued by singer Dion DiMucci for $1 million in damages.

DiMucci, known mononymously as Dion, is suing over the use of his trademark song “The Wanderer” which appeared as part of the in-game soundtrack to Fallout 4. The suit is not about the song’s presence in the game, but rather the song being used for game ads that Bethesda created to promote the title back in 2015.
